The Avnet MicroZed Industrial IoT Starter Kit supports designers’ edge-to-cloud development of Internet-connected solutions and includes all the necessary building blocks for developing a production-ready, IoT-enabled, industrial processing system. The platform is based on Avnet’s MicroZed system-on-module (SoM) with Zynq®-7000 All Programmable SoC from Xilinx and pluggable sensor solutions from Maxim Integrated and ST Microelectronics. The kit integrates the IBM Watson IoT agent on top of a custom-configured, certified image of the Wind River® Pulsar Linux operating system. The provided out-of-box example design uses a standard MQTT messaging protocol to communicate with Watson IoT, which enables registered, secure connection to additional cloud services and applications, including the IBM Bluemix® portfolio. Bluemix provides a rich palette of composable services to rapidly enhance IoT solutions with cognitive capabilities.
STMicroelectronics Sensor Shield
The X-NUCLEO-IKS01A1 from ST Microelectronics is a motion MEMS and environmental sensor evaluation board system compatible with the Arduino UNO R3 connector layout. It is designed around four discrete sensor solutions from STMicroelectronics, which communicate to the MicroZed via an I2C interface. The sensors include:
LSM6DS0: MEMS 3D accelerometer (±2/±4/±8 g) + 3D gyroscope (±245/±500/±2000 dps)
LIS3MDL: MEMS 3D magnetometer (±4/ ±8/ ±12/ 16 gauss)
LPS25HB*: MEMS pressure sensor, 260-1260 hPa absolute digital output barometer
HTS221: capacitive digital relative humidity and temperature
DIL 24-pin socket available for additional MEMS adapters and other sensors (UV index)
Maxim Integrated Thermocouple Sensor
The MAX31855PMB1 peripheral module includes the MAX31855 cold-junction compensated thermocouple-to-digital converter, which performs cold-junction compensation and digitizes the signal from a thermocouple. The module is set up to operate with the included K-type thermocouple. The data is output in a signed 14-bit, SPI-compatible, read-only format. This converter resolves temperatures to 0.25°C, allows readings as high as +1800°C and as low as -270°C, and exhibits thermocouple accuracy of ±2°C for temperatures ranging from -200°C to +700°C for K-type thermocouples.
